Yes， the passenger in the blue truck is Rolf， a dog that is hired to find things people have lost. Within seven years， Rolf and his owner have found close to $400 000 worth of missing items. Among them are watches， Jewelry， tools， money， cows， geese， pigs and other dogs. And what is Rolf' s secret？ His sensitive nose！
The owner of that nose is a ten-year-old German Shepherd. And the owner of the German Shepherd is Svend Anderson. Together they answer the 600 to 700 calls for help that they get each year. Four out of five times they find what they are asked to look for.
